SUMMARY OF THE INVENTION

The present invention provides a cleansing composition for skin or hair,comprising an internal olefin sulfonate (A) having 12 or more and 24 orless carbon atoms (hereinbelow, may also be referred to as “thecleansing composition of the present invention”).

DETAILED DESCRIPTION OF THE INVENTION

Therefore, the present invention provides a cleansing composition forskin or hair which can provide a good durability of foam, rinse feel,give good combability, softness and manageability from during rinsing toafter drying when the cleansing composition is applied to hair, and givegood moist feeling to skin when the cleansing composition is applied toskin.

In light of the above, the present inventors carried out variousstudies. As a result, they found that a cleansing composition which canimpart good combability, softness from during rinsing to after dryingand manageability after drying to hair, and a sufficient moist feelingalso to skin after application, while exhibiting an excellent durabilityof foam and rinse feel as a cleansing agent for skin or a cleansingcomposition for hair can be obtained by using an internal olefinsulfonate having specific number of carbon atoms.

Hereinbelow, the present invention will be described in detail.

The cleansing composition of the present invention contains an internalolefin sulfonate (A) having 12 or more and 24 or less carbon atoms.

The reason is not clear why the cleansing composition according to thepresent invention provides a good durability of foam and rinse feel, andgives good combability and softness from during rinsing to after dryingwhen the cleansing composition is applied to hair, and a good moistfeeling to skin when the cleansing composition is applied to skin. It ispresumed that the internal olefin sulfonate having 12 or more and 24 orless carbon atoms has proper hydrophobicity, and therefore bubbles areeasily broken in a diluted region by rinsing, and washed off, while partof the internal olefin sulfonate is adsorbed on skin or hair to givegood combability, softness and manageability, and to improve a moistfeeling to skin.

<Internal Olefin Sulfonate (A)>

From the viewpoint of improving detergency, foam quality, andfoamability, and a good rinse feel and durability of foam, and also,imparting to hair good combability and softness from during rinsing toafter drying and manageability after drying and a moist feeling to skin,the cleansing composition of the present invention contains an internalolefin sulfonate having 12 or more and 24 or less carbon atoms(hereinbelow, may also be referred to as a component (A)).

In the present invention, an internal olefin sulfonate is an olefinsulfonate obtained by sulfonating an internal olefin (an olefin having adouble bond inside the olefin chain) as the raw material, followed byneutralization and then hydrolysis. It should be noted that the aboveinternal olefin may also have a broad meaning including a trace amountof so-called α-olefin, in which a double bond is present at the C-1position of the carbon chain. That is, sulfonation of an internal olefinquantitatively produces β-sultone, some of which are converted intoγ-sultone and olefin sulfonic acid, which are further converted intohydroxyalkane sulfonate and olefin sulfonate in the process ofneutralization and hydrolysis (for example, J. Am. Oil Chem. Soc. 69, 39(1992)). Here, the hydroxyl group of the hydroxyalkane sulfonate thusobtained is present inside the alkane chain, and the double bond of theolefin sulfonate is present inside the olefin chain. Also, the productthus obtained is mainly a mixture of the aforementioned substances,which may partially contain a trace amount of hydroxyalkane sulfonatehaving a hydroxyl group at the end of the carbon chain or olefinsulfonate having a double bond at the end of the carbon chain. In thepresent specification, each of these products and a mixture thereof arecollectively referred to as internal olefin sulfonate (component (A)),and each of the product is individually referred to as internal olefinsulfonate. It should be noted that hydroxyalkane sulfonate is referredto as the hydroxy form of an internal olefin sulfonate (hereinbelow, mayalso be referred to as HAS), and olefin sulfonate is referred to as theolefin form of an internal olefin sulfonate (hereinbelow, may also bereferred to as IOS).

Also, fromthe viewpoint of softness of the hair during rinsing, manageabilityafter drying, and a moist feeling on the skin, the number of carbonatoms in the internal olefin sulfonate of the component (A) is 24 orless, preferably 20 or less, and more preferably 18 or less. Also, fromthe above points, the number of carbon atoms in the internal olefinsulfonate of the component (A) is 12 or more and 24 or less, preferably14 or more and 20 or less, and more preferably 16 or more and 18 orless. These hydroxy form and olefin form containing various numbers ofcarbon atoms are derived from an internal olefin to be used as the rawmaterial, and a hydroxy form and an olefin form containing differentnumbers of carbon atoms from those described above may also becontained.

Also, themethods used for measuring various physical property are as follows.

(1) Conditions of Measurement

(i) Method for Measuring the Position of a Double Bond in the InternalOlefin

The position of a double bond in a raw material internal olefin wasmeasured by gas chromatography (hereinbelow, abbreviated as GC).Specifically, an internal olefin was converted to a dithiated derivativeby reaction with dimethyl disulfide, and each component was separated byGC. As a result, the position of a double bond in an internal olefin wasfound based on the peak area of each component.

The apparatus and analytical conditions used for the measurement are asfollows. GC apparatus (trade name: HP6890, the product ofHewlett-Packard Company); Column (trade name: Ultra-Alloy-1HT capillarycolumn, 30 m×250 μm×0.15 μm, the product of Frontier Laboratories Ltd.);Detector (flame ionization detector (FID)); Injection temperature of300° C.; Detector temperature of 350° C.; and He flow rate of 4.6mL/minute.

(ii) Method for Measuring the Mass Ratio of Hydroxy Form/Olefin Form

The mass ratio of hydroxy form/olefin form of the internal olefinsulfonate was measured by HPLC-MS. Specifically, the hydroxy form andthe olefin form were separated by HPLC and each form was identified byseparately analyzing with MS. As a result, from the resulting HPLC-MSpeak area, the fraction of each form was obtained.

The apparatus and analytical conditions used for the measurement are asfollows. HPLC apparatus (trade name: Agilent technology 1100, theproduct of Agilent Technologies, Inc.); Column (trade name: L-column ODS4.6×150 mm, the product of Chemicals Evaluation and Research Institute,Japan); Sample preparation (diluted 1000-fold with methanol); Eluent A(10 mM ammonium acetate in water); Eluent B (10 mM ammonium acetate inmethanol), Gradient (0 minute (A/B=30/70%)→10 minutes (30/70%)→55minutes (0/100%)→65 minutes (0/100%)→66 minutes (30/70%)→75 minutes(30/70%); MS apparatus (trade name: Agilent technology 1100 MS SL(G1946D); and MS detection (anion detection m/z 60-1600, UV 240 nm)

(iii) Method for Measuring the Content of the Raw Material InternalOlefin

The content of the raw material internal olefin of the internal olefinsulfonate was measured by GC. Specifically, ethanol and petroleum etherwere added to an aqueous solution of internal olefin sulfonate, followedby extraction to give olefin in the petroleum ether phase. As a result,from the GC peak area of the olefin, the amount thereof was quantitated.The apparatus and analytical conditions used for the measurement are asfollows. GC apparatus (trade name: Agilent technology 6850, the productof Agilent Technologies, Inc.); Column (trade name: Ultra-Alloy-1HTcapillary column, 15 m×250 μm×0.15 μm, the product of FrontierLaboratories, Ltd.); Detector (flame ionization detector (FID));Injection temperature of 300° C.; Detector temperature of 350° C.; andHe flow rate of 3.8 mL/minute.

(iv) Method for Measuring the Content of Inorganic Compounds

The content of inorganic compounds was measured by potentiometrictitration and neutralization titration. Specifically, the content ofNa₂SO₄ was quantitated by measuring sulfate ion (SO₄ ²⁻) bypotentiometric titration. Also, the content of NaOH was quantitated byneutralization titration with diluted hydrochloric acid.

(v) Method for Measuring the Content of the Paraffin Component

The content of the paraffin component was measured by GC. Specifically,ethanol and petroleum ether were added to an aqueous solution ofinternal olefin sulfonate, followed by extraction to give paraffin inthe petroleum ether phase. As a result, from the GC peak area of theparaffin, the amount thereof was quantitated. It should be noted thatthe apparatus and analytical conditions used for measurement are thesame as those used for the measurement of the content of the rawmaterial internal olefin.

(vi) Method for Measuring the Content of Internal Olefin Sulfonate inwhich a Sulfonate Group is Present at a C-2 Position

The linkage position of the sulfonate group was measured by GC.Specifically, the resulting internal olefin sulfonate (A) was reactedwith trimethylsilyldiazomethane to form a methyl-esterified derivative.Then, each component was separated by GC. Each of a peak area wasregarded as a mass ratio, and the content of internal olefin sulfonatein which a sulfonate group is present at a C-2 position was quantitated.

Theresulting crude internal olefin was transferred to a distillation flaskand distilled at from 134 to 138° C./from 75.0 to 78.8 mmHg, whereby100% pure internal olefin having 12 carbon atoms was obtained. Thedouble bond distribution of the resulting internal olefin was 0.5% bymass at C-1 position, 33.1% by mass at C-2 position, 23.7% by mass atC-3 position, 21.2% by mass at C-4 position, 15.0% by mass at C-5position, and 6.8% by mass at C-6 position.

(3) Production of an Internal Olefin Sulfonate

Production Example 1

Using a thin film sulfonation reactor (14 mm in inner diameter and 4 min length), the sulfonation reaction of the internal olefin having 16carbon atoms produced in Production Example C was carried out by passingthrough sulfur trioxide gas containing a concentration of SO₃ at 2.8% byvolume, while passing cooling water of 20° C. through the outer jacketof the reactor. It should be noted that the reaction molar ratio ofSO₃/internal olefin was set at 1.09.

The resulting sulfonation product was added to an alkaline aqueoussolution containing 1.2 times the molar amount of sodium hydroxiderelative to the theoretical acid value (AV), followed by neutralizationat 30° C. for one hour while stirring. The resulting neutralized productwas hydrolyzed by heating at 160° C. for one hour in an autoclave,whereby a crude product of sodium C16 internal olefin sulfonate wasobtained.

Then, 300 g of the crude product thus obtained was transferred to aseparatory funnel, to which 300 mL of ethanol was added. Then, 300 mL ofpetroleum ether was added per operation, whereby oil-soluble impuritieswere removed by extraction. At this time, inorganic compounds (mainlycomposed of sodium sulfate) which were precipitated at the oil-waterinterface by the addition of ethanol were also separated and removedfrom the aqueous phase by the oil-water separation operation. The aboveoperation was repeated three times. Then, the aqueous phase side wasevaporated to dryness, whereby sodium internal olefin sulfonate (1)having 16 carbon atoms was obtained. The content of the raw materialinternal olefin was less than 100 ppm (below the GC detection limit) andthat of inorganic compounds was 1.9% by mass. The above results areshown in Table 1.
